INDEXING DEVICE.

Application filed April 22, 1924. Serial No. 708,261.

' mary object the provision of a device of this character, which issimple and" inexpensive of construction and which will adapt itself toloose leaf binders of well-known forms and provide same with means atthe jointor hinge or at one edge of the binder which will visually indexthe contents of the binder and enable the nature of said contents orname of the party whose record is kept to be clearly and instantlydiscernible at a glance and without the necessity of opening the coversof the binder, when such information is desired.

Another object of the invention is to provide a device of this characterwhereby a number of binders can be arranged in stack formation and insuch manner that the index portions of the respective binders will bedistinguishable from each other and prominently displayed.

Another object of the invention is to provide a device of the characterwhich shall be strong and durable, light of weight, and of a designwhereby the index indicia can be printed upon a suitable slip of papercard or the like and arranged in a transparent protective casing of thedevice.

The invention is fully illustrated in the accompanying drawing, but theimportant details thereof may be varied, and so it shall be understoodthat the invention is not limited to the specific details shown anddescribed, as long as they are within the spirit or scope of the claims.

Figure 1 is a perspective view of a loose leaf bind er showing anapplication of my invention thereto.

Figure 2 is a perspective view of my invention initially associated witha package of loose leaves before arranging same between the back boardsof the binder.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is a section on line 44: of Figure 2.

In carrying the invention into practice, use is made of a loose leafbinder hav ing the customary back boards or cover members (11) and (12),the former having a hinged section (13) and the latter a similar section(14). Said hinged section (13) is provided with leaf-engaging posts orelements (15) adapted to be threaded or passed through the usual holes(16) in the leaves (17) and through holes (18) in the hinged section(14-). Screws or suitable retaining devices (19) are engageable withsaid posts and 'are adapted to be brought to bear against one side ofthe section (1 1) when the cover or back members are clamped against theleaves. Y

Mounted at what I call the hinge end or joint of the binder is myimproved indexing device (20), the same consisting of a U- shapedleaf-receiving member (21) formed of cloth between the folds of whichthe adjacent ends of the leaves are mounted and snugly arranged. Inother words, this member is of a size to accommodate a given number orstack of normally loose leaves so that the upper and lower folds of themember come parallel with the top and bottom leaves respectively whenthe member is in an applied position. It shall of course be understoodthat said member can be made in various sizes to accommodate itself to agiven number of leaves and to leaves of re spectively varying widths orbinders of different sizes. The device is preferably coextensive withthe width of the leaves so that the ends of the device come flush withthe side edges of the binder.

The connecting edge wall (22) between the upper and lower folds of themember (21) is reinforced by a longitudinal strip of stiffening materialThe member (21) is nested within a correspondingly shaped receptacle(24) of flexible transparent material and same has its flanges 25-25cemented or otherwise suitably secured to the aforesaid upper and lowerfolds of the member (21), said receptacle has a connecting wall (26)open at its ends (27 and free between said ends from the edge wall (22)so that the latter and the former can be spread apart or separatedrelatively for a purpose to be hereinafter described.

The ends of the flanges 25-25 are provided with slot holes (28) whichregister with corresponding holes (29) in the respective upper and lowerfolds of the member (21) and with the holes (16) in the loose leaves ofthe binder. In this manner the posts (15) when passed through all of thesaid holes serve to retain the device in position.

By separating the wall (26) from the wall (22) it is seen that a pocketis formed therebetween for insertion and retention therein of a slip orcard (30) on which the. indexing indicia are printed or otherwisesuitably arranged and that incident to the described location of themating posts of the'device, said slip or card (30) is clearly visiblefrom the hinge end or back of the binder. In this 'manner a number ofsuch binders can be arranged in stack formationwith the 1ndex surfacesexposed one directly above the other as will be understood. My improvedindexing device is freely separable from the binder and therefore isinterchangeable and can be removed from one binder and applied toanother if desired. Its construction also enables one to quickly andconveniently attach it to a binder. without the necessity of changes inthe construction of the latter.

lVhile I have shown the preferred embodl ment of my invention, it shallbe understood that changes in the construction of the device and obvioussubstitutions may be made within the scope of the hereto appendedclaims.

It should be observed that my indexing device does not restrict the bookto a certain number of sheets, because it is always possible to place anadditional series of sheets on top or below the indexing device.

I claim:

1. An indexing device comprising two U- shaped members nested togetherand hav ing portions defining a receptacle for an index card, one ofsaid members formed of transparent. material to expose the indicia ofsaid card, the parallel portions of the said members being adapted to beclamped inside the cover boards of a loose-leaf binder.

2. As a new article of manufacture, an indexing device for loose leafbinders comprising a member formed of transparent material provided withparallel flanges and a connecting wall, the respective flanges havingalined openings for the reception of the leaf-engaging posts of thebinder to thereby hold the device in relatively permanent position withrespect to the leaves and to maintain a positionof the connecting wallagainst one edge of the binder so that an index card can be insertedbetween the connecting wall and the adjacent edges of the leaves of thebinder.
